Wastewater Recycling

1. What is Decentralised wastewater treatment system?
Decentralised wastewater tretment system (DWWTS) is an approach consisting of different technologies to provide wastewater treatment solutions for small, individual or cluster type facilities. It is a sustainable method to treat domestic wastewater which is generated from the office campuses, residential societies and institutional premises.
2. Why should I adopt this method?

The research as a part of COE activity at CSE includes policy research on decentralized wastewater management (DWWT), rainwater harvesting (RWH) and water efficiency(see presentation). As a part of CoE mandate, CSE has prepared and submitted various reports and policy papers in the area of sustainable water management to Ministry of Urban Development (MoUD).

The wastewater recycling system at CSE has been designed to treat 8000 litres per day based on the assumption that at any given moment at least a 100 persons would be ocupying the premises. The components involved in treatment are a settler, a baffled reactor and a planted filter.

The treated wastewater is stored in an underground sump. This water is used for gardening.
